Slag powder in concrete role is reflected in the fine aggregate effect and chemical activity effects in two ways. Suitable for the preparation of the flexural strength of high-strength, high-performance concrete and roads, bridges and other demanding concrete works; in mass concrete works, concrete works underground, underwater and marine engineering concrete concrete engineering and other aspects of great Advantage.

On the vertical roller mill turnkey projects, the Chaeng mechanical innovation. In Meng Power Group's annual output of 1 million tons of slag powder production line, a number of innovative technological features to ensure high productivity, low energy consumption of the smooth operation of the entire slag powder production lines, mainly in the following aspects:

1, separate wet and dry

That slag vertical mill and feed back (outer loop) and separate wet slag into the mill. Wet slag by spiral reamer feed mill stand, in addition to iron feed back by the rotary feeder vertical mill feed chute through.

Since the slag has its own hydraulic weak, dry and wet slag vertical mill mixed material back hydration reaction will occur weakly caking children, so the conventional mixing feed screw reamer program will cause compaction, resulting in transmission capacity reamer decline even reamer shaft fracture.

2, the outer loop using pipes buried scraper hoist combination Separators

Using pipes buried scraper hoist vertical mill separator combination delivery efflux, since the feed back is always in the housing, it is possible to prevent dust spills back to the material, can greatly improve the vertical mill surrounding environment; traditional except conveyor belt hanging iron hoist combination, the conveyor belt sticky material, resulting in the suspension of operation of separator air flow will cause a large amount of dust that location, the surrounding environment is poor.

3, slag former into the mill provided steady flow positions (middle position)

Setting steady flow of slag from the roller mill and warehouse closer to (located in back of the loading frame), under steady flow of slag through the belt scale measurement positions after a short drop to the belt, belt conveyor into the slag spiral reamer into the mill.

Setting stable chamber allows more uniform feed roller mill, vertical mill run more stable.

4, stop grinding material by efflux efflux warehouse reentry stand mill

Vertical mill stop grinding, the outer discharge tube through a slide back into the outer row of storage memory on the frame material, the outer row positions under measurement, said after the start grinding again, again fed by a metering called metering roller mill grinding.

5, set the dust collector on the delivery chute corridors

Dust collector disposed in the chute between the elevator corridor finished powder collecting device to make the chute and finished hoist always running under negative pressure, to avoid housing Mifengbuyan caused dust to escape.

On the stand mill turnkey projects, the Great Wall of mechanical innovation. In Bangladesh Power Group's annual output of 100 tons of slag powder production line, a number of innovative technological features to ensure high productivity, low energy consumption of the smooth operation of the entire slag powder production lines, mainly in the following aspects:

9, other innovative technology
